MOUNTING FOR AIR DEFLECTOR Filed April 8, 1963 INVENTOR.

FRANK R. KNAEBE ATTORNEY United States Patent 3,214,123 MOUNTING FOR AIR DEFLECTOR Frank R. Knaebe, 6048 N. 114th St., Milwaukee 16, Wis. Filed Apr. 8, 1963, Ser. No. 271,124 1 Claim. (Cl. 248-224) This invention relates to an improvement in an air deflector for directing moving air exteriorly of a building to the interior thereof through an open window.

The primary object of this invention is to provide an air deflector which may be removably mounted on either side of a window casement or preferably on either side of a screen sash at the will of the user and without the requirement of any tools.

It is also an object to provide for an air deflector mounting means comprising two substantially identical brackets, one secured to an intermediate point of one side of a screen sash and the other on the corresponding part the other side of the sash, each adapted for mating with the bracket on the deflector.

Another object is to provide a pair of identical socketed brackets for a window casement or screen sash and an air deflector bracket having substantially identical portions, one portion receivable in one of the sockets of one of the brackets and the other portion, upon inverting the air deflector, receivable in the socket of the other bracket.

A further object is to provide relatively simple and inexpensive means for mounting an air deflector in either of two directions relative to an open window and will not require the services of a skilled workman but which may be attached to a window and reversed, according to the requirement of air movement, by the occupant of the room to be aired.

A still further object is to provide an air deflector which may serve to direct moving air through a window into a room or, at the option of the user, serve to divert moving air exteriorly of a house and entrain the air adjacent the window thereby causing the air in an adjacent room to flow outwardly through the window.

Another object is to provide a minimum number of bracket units for mounting an air deflector in either of two positions relative to a window and relative to the direction of air flow exteriorly of the window.

Other advantages afforded by this invention will become apparent in the following specification of the drawings, in which FIG. 1 is a fragmentary view, in side elevation, of a window and screen sash as seen from the exterior of a building.

FIG. 2 is a horizontal sectional view taken on the line 2-2 of FIG. 1.

FIGS. 3 and 4 are enlarged views, illustrating a bracket for mounting on a window casement or screen sash.

FIGS. 5 and 6 are enlarged views illustrating a bracket for mounting on the air deflector shown in FIGS. 1 and 2.

FIGS. 7 and 8 are enlarged views illustrating the brackets shown in FIGS. 3 through 6 in cooperative relationship.

Mounted in the window casement 1 is a screen 2. The screen sash includes two relatively spaced-vertical side members 3 and 4 secured together by a bottom member 5. Mounted on each of the vertical members is bracket 6, each comprising a flat-rectangular base portion 7 having a screw receiving hole 8 at each corner. Integral 3,214,123 Patented Oct. 26, 1965 lice with the base portion 7 is lug or socket member 9 which is tubular to provide a vertically extending socket.

Secured to the air deflector 10, intermediate the vertical length thereof, is a second bracket 11 having a rectangular base portion 12 with a screw receiving hole 13 at each corner. Integral with the base portion 12 is a flat-rectangular arm portion 14 having a pin 15 extending therethrough to opposite sides thereof in a plane substantially parallel to the flat surface of said base and normal to said arm portion.

The diameter of the vertical hole in the socket 9 is such as to freely receive either projecting end of the pin 15. The air deflector 10 is preferably slightly arcuate in horizontal cross-section. When the deflector is mounted, as shown in full lines, on the right side of the window, as viewed in FIG. 1, the lower projecting end of the pin 15 is positioned in the socket of the bracket 6 on the screen sash side 4 and the arm 14 of the bracket 10 rests on the lug 9. To prevent swinging movement of the air deflector, the arm on the bracket 10 is forced on one side against the adjacent portion of the base 7 on the bracket 6. Thus air moving in the direction from left to right, relative to FIGS. 1 and 2, will be forced to change its di; rection upon contact with the deflector and caused to pass through the window. In the event the direction of flow of the air is in opposite direction, from right to left relative to FIGS. 1 and 2, the user may remove the deflector from the right side of the window relative to FIG. 1, invert it so that bracket 10 on the deflector is on the left relative to FIG. 1 and mounted on the bracket 6 on the screen sash side 3 as indicated by the broken lines. Thus air will be directed through the window.

However, the deflector 11 may be left in the position as shown in full lines in FIG. 1 and, if the air is moving from right to left, it will be deflected away from the window and thus entrain the air adjacent thereto and cause the flow of air outwardly of the window. The same effect will be produced when the deflector is mounted as shown by the broken lines and the air is moving from the left to the right relative to FIGS. 1 and 2.

It will be observed that I have provided a deflector which requires only two identical brackets for attachment to a window screen sash or to the window casement, one on each side and each adapted to receive a single reversible bracket on an air deflector.

From the foregoing it is obvious that I have provided novel means for mounting an air deflector on either side of a window casement or screen sash, that these means are of simple, relatively inexpensive, of a minimum number of parts, and do not require the services of an expert when applying them for use.

It is also apparent that the deflector disclosed herein may be used to direct air in one direction through a window or to entrain air adjacent the window and cause the air to move in the opposite direction through the window.

I claim:

A mounting for a window air deflector or the like, said mounting comprising in combination a first bracket having a flat base portion adapted for fixed attachment to a vertical sash member or the like and having a socket member integral therewith and projecting in normal relationship thereto, the axis of the socket being dispos d in a plane substantially parallel to the surface of the said flat base portion of said first bracket, a second bracket having 3 4 a fiat base adapted for fixed attachment to an air defiec- References Cited by the Examiner tor and having an arm integral therewith and projecting UNITED STATES PATENTS angularly from said base in a plane normal to said base,

and a pin carried by said arm and projecting from opposite 31230 1/61 Ehrman 16 17O sides thereof in a plane substantially parallel to the surface 5 158987 1/75 semen 16*170 of the said flat base, the projecting ends of said pin being 1096313 5/14 Megredy 98*44 receivable in said socket, said last mentioned arm having a 61 11/48 Wolff 98-44 flat face paralleling said pin and complementary to the FOREIGN PATENTS surface of said flat base portion of said first bracket, 572,612 3/59 Canada whereby when said pin is in said socket, said bracket will 10 be held in relatively fiXed-non-rotative relationship.
